Can you do a or b, or do you need to do both?

Re: a), which terminal do you need to disconnect?

 

I don't think it matters, but I remove the loop from the positive terminal post instead of messin with the red cap cover.

 

Dexter,

Because you have the TC installed. Reset the ECU give you instant kick at take off. For people with stock TC, the outcome will not be that obvious.

 

Rather than to mess around with a wrench each time to remove the battery terminal would the following product be a good choice? At $12 it seems like a good investment for quick and easy way to reset the ECU. Has anyone tried this product?

Nah - it takes probaby just as long to turn the **** as it does to turn the socket a few times, and I don't want to add any gadgets into the power flow....but good eye.

 

One more time...

 

from what I got.....either will sufice.

 

Oh, sorry Bit - yeah, just one will work fine.

I was hoping you'd be singing the praises of 'the reset' when I got the notification!

 

Here's an old link < click here > that gives a bit more detail on how to actually pull the fuse and exactly where it is.

One thing that isn't mentioned - once you open up the fuse box, there is a little fuse puller that Lexus nicely provides for you included in the box. The first couple of times I reset mine, I didn't know it was there... it's much easier using it than using your fingers.

I also have the Precision Industries Torque Converter - and can definitely feel a big difference when I reset the ECU.

 

Thanks. It seems like pulling the fuse is preferable to unplugging the battery since pulling the fuse won't lose seat memories, radio stations, etc., right? Or is that info all stored in the same ECU!?

 

I don't know if it is true, but when you pull the fuse, are you suppose to try to crank the engine a couple of times and then put the fuse back in. My friends used to reset their ECU's on their Hondas and they would pull and then try to start a few times. It worked for them....but then again, Hondas are anywhere near Lexus.

 

hi guys,
this is not a trick,it really works.after you do just try to drive just a little bit more agressively,you will be spinning your tyres so fast ,you'll not believe it.

For those who have not yet done this, I can now vouch for the time it takes to recover from pulling the ECU fuse (yes, the radio and seat memory were lost). I pulled the fuse and left it out for about 30 minutes. Then, in between Battlebot rounds and a commercial, I replaced the fuse and cover, reset 6 radio stations (not all), and reset the seat memory (everything was still in the same position). If I also notice the improvement others have noted, I’ll do it once a week – only takes a couple of minutes.

Dexter, thanks for bringing this up – hard to believe that it’s gone unnoticed for over 6 months (since the previous thread). I guess I missed ‘cause I still had the SC and wasn’t visiting the GS forum often and wouldn’t have known what it was all about anyway.

I'll be looking forward to the drive to work tomorrow.

 

Just had to do it at least once!!!!

Haven't driven it yet since I just pulled it at 10:30 and installed at 11:00 p.m....While I was waiting I was trying to get some freaking ink off of the driver seat I didn't do it..... read about that on the other thread.

 

Just did it this morning by pulling the fuse. The car feels great. Engine runs free, with it going all the way to redline in auto when I stomped on it to enter a freeway!

Bit, since you have nav also, here's what you'll lose; seat memory, electric clock, trip computer data, last climate setting, and of course the tranny parameters. Your nav memory will be retained, along with your radio stations.
